Worth Four Dot Test

The Worth Four Dot Test is a simple eye assessment to check if your eyes are working together properly, specifically checking for double vision or eye alignment issues. You wear special glasses with different colored lights, and when you look at a specific target, you'll see either four or fewer dots. Seeing four dots usually indicates normal fusion or eye teaming, while seeing fewer or different numbers suggests possible eye alignment problems or suppression of one eye’s view. The test helps eye care professionals evaluate binocular function and guide treatment if needed.
